Question

I am using Boost asio 1.48. Is it possible to re-use a single boost::asio::io_service instance for multiple listening sockets that are open simultaneously?

The docs say its share-safe, but I am not sure if that is already a positive answer.

Answer 1

Yes, you can, and you should. And you can use that same io_service to handle those sockets, handle timers, handle requests you post to it, and so on. The whole point of an io_service is to act as a central dispatcher for work of all kinds.
